DC SYSTEM
Your Chaparral boat has two (2) electrical systems:
a 12 volt, direct current (DC) battery and a 120 or
220 volt alternating current (AC) system. The 12 volt
direct current (DC) electrical system draws its power
from the batteries, which are kept charged by an
engine-driven alternator and/or AC converter. The
voltmeter on the main distribution panel and control
station instrument panel shows the battery charging
rate when the engine is running. Each battery bank
can be checked with the battery voltage test switch
only on the salon DC distribution panel. All DC
power is distributed through the battery selector
solenoid. The 12 volt dash electronics fuse panel is
protected by the electronic control breaker on the
main DC breaker panel located on the aft bilge com-
ponent board.
The negative terminal of each battery bank is con-
nected to the grounding studs of the main engine(s)
and generator. This type of negative ground system
is the approved system for marine DC electrical sys-
tems. If you add additional equipment to your boat,
it must be adaptable to the negative ground system.
BATTERIES
The batteries installed in your boat have been cho-
sen for their ability to supply power for lights, to start
the engine or generator, and the accessories, as
well their ability to furnish power to the DC system.
The following table describes the recommended
marine cranking batteries to install in your boat.
*COLD CRANKING AMPS@ 0º F
The main engine cranking batteries consist of one (1)
31 DCM 12 volt battery for each engine. There are
two (2) Group 31, 12 volt marine batteries connected
in series that are dedicated to suppling all house
operations. (Figure 7.1)
To Remove The Battery Cables
1. Turn OFF all items drawing power from the
batteries.

DANGER: Never use an open flame in the bat-
tery storage area. Avoid striking sparks near the
batteries. A battery will explode if a flame or
spark ignites the free hydrogen given off during
charging.
CAUTION: While the engine or generator is run-
ning, the battery terminal clamps must not be
loosened or detached, nor should the battery
solenoid switch(es) be turned off. The alternator
and other electronic units will be damaged.
